The Hamiltonian is reduced to a convenient form by similarity transformation. The matrix representation of the Hamiltonian acting on a partially ordered state space is obtained in an upper triangular form. Consequently the diagonal elements become the energy eigenvalues.1 figureHigh Energy Physics - TheoryStatistical MechanicsMathematical Physicstext
